Natural & Essential Oil SPF

Raspberry seed oil, olive oil & coconut oil have been shown to have the highest SPF values. These are calculated using in vitro (lab) absorbance data. FDA-evaluated sunscreen values are measured in vivo (on human volunteers), but results from two methods are usually equivalent.

Protection will vary by brand & harvest. Consider the values provided here and in supporting literature to be approximate.

Essential oils are not recommended for use as sunscreen. Fixed (pressed) oils are more stable than volatile (essential) oils.

Raspberry Seed Oil SPF Is Highest

According to a group of researchers in Canada, France & China, raspberry seed oil has a SPF between 28-50 and may act as a broad spectrum UV protectant:

The optical transmission of raspberry seed oil, especially in the UV range (290-400nm) was comparable to that of titanium dioxide preparations with [SPF] ... values between 28-50
